Small Hive Beetles
"The small hive beetle can be a destructive pest of honey bee colonies, causing damage to comb, stored honey and pollen. If a beetle infestation is sufficiently heavy, they may cause bees to abandon their hive."

All Italian hives with SHB in are burned on sight. The officials are trying to stop its spread.There are 20.000 German hives wintering in Italy for the pollination services and these might well spread it fast around Europe. I am so much against migratory beekeeping which is spreading fast pests and diseases!
I asked treatment-free beekeepers from US what they do about SHB and this is the answer I've got:
"Keep a strong hive, and make sure you have enough bees to cover ALL your protein sources. And remember, your protein sources include pollen, pollen patties, brood, larval cocoons, even dead bees. If you don't have enough bees to cover all these, you need to remove some protein."
